I have a brand new copy of Saint's Row 2 on the way to me for $39.71. Here's how I did it:

I had it in my rental queue at Gamefly and made sure I had an open slot in my rentals (I'm on the two-games-at-a-time plan) on Sunday. Last night (Monday) I received the notice that Saint's Row 2 had shipped to me. So I went to Gamefly and hit "Keep It." Because I've been a Gamefly member for more than 12 months, I get 10% off any game purchases, even if they're games that have *just* released. Every 3 months I get a $5 off coupon, and I'd saved this one for just this instance.

$46.99 - Gamefly "Keep It" price
+$2.42 - Tax
+$0.00 - Shipping
-$4.70 - Loyalty level 3 (10% off)
-$5.00 - Coupon
=====
$39.71 - Total

That's not half bad, compared to $59.99 plus tax at standard retail. It's shipped from Tampa, and I'm in Orlando, so I expect I should have the game tomorrow (Wednesday), with the box and documentation coming probably Thursday or Friday.

This site has inspired me to find new and better ways of saving money on my games, and Gamefly is awesome for this sort of thing. My next cheap-ass trick will be using the $25 gift card I earned from E-Rewards toward my purchase of Fable II at Gamestop. Between those and the 360 Elite I just received today from Dell.com, it's a good month for me with gaming deals.
